 The temporal extent or temporal extent or TE not that anybody uses that acronym, but I will so TE temporal extent refers to the fact that every instance of behavior occurs during some amount of time Pretty often it sounds a little bit heady right or heady, but heady heady heady whatever the point is is that behavior takes time to happen and It has a real effect on the world in some way shape or form, right? And then you can measure that effect This is kind of that one of those key pieces of behavior that all measurement and all of the other stuff that we do with behaviors based on Basically, it just means that the behavior is real and it has to happen Within the context of the real world. We're not talking about metaphysics here We're talking about just plain old standard old, you know standard model physics is nothing special Behavior occurs and it takes time to occur some behaviors are really quick Some behaviors are longer Right, so they have a temporal extent though, right? So there's all that stuff in there So you get it. It's just stuff the behaviors do
